I have a bantam Cochin that hatched 7 Guinea keets this morning. When I was at the farm store today I noticed Barred Rock chicks. They are 10 days old. I couldn't resist and brought home 4. I put the chicks under the hen tonight. She didn't seem to mind and the chicks snuggled right under her. What are the chances she will accept them in the morning, and is there anything I can do to help?
